Abstract
The invention provides a manufacturing method of a high-whiteness bamboo-charcoal viscose fiber, which comprises the following steps: soaking the raw materials mainly comprising bamboo chemical fiber pulp, squeezing, pulverizing, aging, sulfidizing, dissolving, degassing, filtering, spinning into yarn, post-processing and drying; and in the course of processing, adding nano white-crystal pulp, wherein the nano white-crystal pulp accounts for 0.5-10% of the alpha cellulose by weight. In the invention, the nano white-crystal pulp is added in the course of manufacturing the bamboo-charcoal viscose fiber to manufacture the high-whiteness bamboo-charcoal viscose fiber. The prior bamboo-charcoal viscose fiber can be only black or grey; however, the high-whiteness bamboo-charcoal viscose fiber has high whiteness which is greater than or equal to 60%. The high-whiteness bamboo-charcoal viscose fiber can be colored with various dyes, and has the functions of bacterial inhibition, far infrared emission and negative oxygen-ions, thereby having wide application range.
